The Are You A Blockhead Test

We all know someone who is a real pain in the ass. Are you one of those people? Take this short test and find out if you drive your fellow human being's crazy with your irritating behaviour.
In this test a "blockhead" doesn't only mean a stupid person as its definition says, but also someone who treats other people with neglect and disdain.
Please take the result of this test very seriously and get offended.
